LOCK.

Application filed September The `lock is particularly applicable tofront doors, and comprises thumb latch means, and key and knob operatedmeans to retract a single draw bolt.

It is prefeable in so called front door locks to provide the door on theoutside with a handle, thumb vlatch draw bolt retracting means and keyope ated draw bolt retracting` means; and on the inside with knoboperated draw bolt retrac'ting means.'

An object of my invention is-to provide a novel lock of this characterthe draw bolt of which maybe independently retracted either by a knob,key, or a thumb latch.

An object is to provide a novel lock of this character in which each oneof thediaw bolt rctracting means is operable, irrespective of whether ornot the other retracting means are rigidly held in normal position.

'Another object is to provide a novel lock of this character, in whichone or all of the draw bolt retracting means may be securely lockedAfrom the inside of the door.

A further object is to provide a novel lock of this character in whichthe thumb latch means may be locked from the inside of the door andstill permit retraction of the draw bolt by operation of either the knobor key operated retracting means.

Further objects are to provide a lock which is simple in construction,inexpensive to manufacture, andeflicient in operation.

Advantages of my invention are to provide a. lock, the body of which maybe formed in a single casting, 4and which may be quickly and easilyinstalled in a door.A

This application includes certain novel features more particularly shownand described in my copending application filed August 3l, 1925, SerialNumber 63,548; and may be said to apply the key and knob op; erated lockshown in said application to a front door.

@ther objects, advantages and features of invention may appear from theaccompanying drawing, the subjoined detailed description and the.appended claims,

VFig. l() is an end view of the key operated draw bolt retractingmember.

To prepare the door or the like A, to receive my novel lock l providethe same with a transverse bore B, and with a bore C that extends fromthe bore B, at right angles to the axis thereof, to the free or outeredge D of the door, and ai recess E which depends from, and communicateswith, the bore B, and extends vertically in such door at right angles tothe axis of the bore C.

My invention comprises a tubular locll body i. which is mounted in thebore B and said body l has an externally threadedex# tension 2 on oneside thereof. The extension 2 .is preferably cast integral with the bodyl but it is understood that the Vsame maybe a separate part more clearlyset forth in my above referred to copending application.

Thumb latch supporting means in the form of a tube 23 depends from thebody l and is adapted to be received in` the recess E. The `tube 3 maybe threaded to the body 'l or it may be preferable to die cast the tube3 integral with the lock body l and extension 2.

A draw bolt 4 is provided at its inner end with a crosshead Ll and saiddraw bolt in cludes a sleeve 5 which extends toward the free edge D ofthe door and is 4journalled in an orifice 5" formed in the body l. Thecrosshead 4 and sleeve V5 is providedwith a bore 6 in which )in 7 isadapted to slide ingly lit. The pini? is provided with a reduced end 7vthat extends through the body 1 and is riveted over at its outer end tosecure the pin to the body 1. The pin 7 serves to support the draw bolt4 `and Iacts as a 'guide for the saine. A compression spring 8 surroundsthe pin T and operates between the ci'osshead 4 and lock body and tendsto normally hold the draw bolt in latching position.

The draw bolt also includes Ia latch member tha-t is formed with athreaded shank 10 which is threaded into vthe sleeve 5 a predetermineddistance so that the latch member extends trom the tree edge oft thedoor a sutlicient distance. A rguide plug 11 is driven into the outerend ot the bore C -iiush with the edge D to close said bore, -and saidplug is provided with an opening 12 in which the latch member 9 isadapted to slide. The outer periphery ot' the Iplug 11 is serrated as at13, so 'that the plug 12 will not accidentally protrude beyond lthe:free edge D of tlie door.

Knob operated draw bolt retracting means f 14 is provided to retract thedraw bolt from the inside of the door and such means coinprises a -disc15 'formed on the inner end of an oscillating shaft 16 which entendsfrom the disc 115 land is jou'rnalled in the eXtension 2. The disc 15 ismounted between the closed rend ot the lock body 1 Vand the crosshead 4and is yot sufficient thickness to fill the space therebetween so lthatend play of the shaft 16 is .practicallyY eliminated.

The outer Iend of the shai't 16 may lbe reduced in diameter if desiredand yis threaded as at 17 to receive a 'handle 18 which bea-rs againstthe shoulder 19 't'ormed by reducing the outer end of 'shai't 16.

An arcuate lug 20 formed on the disc 15 projects inwardly therefrom andthe crosshead 4 rests against both ends of said lug' under pressure xo'tithe spring 8. As the shaft 1.6 is oscillated either to the right orleft by the fhafndle 18 one end of the lug 20 w-ill Jforce lthecrosshead 4 against the tension Iot spring 8 and thereby retract thedraw bolt 4.

Key operated draw bolt retracting means is provided to retract vthe drawbolt troni the outside of the door and comprise a cylindrical key lock21 which is screwed into the bodav 1 in axial a-linement with the shaft16. A disc 22 having an arcuate :lug'23 similar to disc 15 and lug 2()is secured to the key operated tumbler 21 ot the lock 21.

The ends ot the lug 23 rest against lthe crosshead 4 in the same 'manner.as before described in connection with the lug 20. lh en `the tumbler.21 is oscil-lated the dra-w bolt 4 will be retracted, irrespective ofwhether or not the handle 18 is rigidly held.

-A cover plate 24 is secured to the inside of the -door by any suitablemeans. such as screws 25, and the shaft 16 Iextends therethrough. Aclamp nut 26 is threaded onto the extension 2 and has a shoulder 26 thatbears against the plate 24.

An outside cover plate 27 is secured to the outside yot the door A bylany suitable -mea-ns such as 'screws 28 and lis provided with anorifice 27 through which the key lock 21 protrudes. A sleeve 29 threadedonto said lock bears against the plate 27 and clamps the door betweenthe shoulder 26 and the inner end ot said sleeve 29 and thus positionsand iirmly holds the lock body 1 in the bore B.

A bolt 30 threaded into the plate 27 eX- tends through the tube 3adjacentthe lower end thereotland nuts 30 threaded to said bolt 30 onopposite sides ot the tube serve vto position and hold the tube in rigidposition. A suitable handle 31 ot any desirable contour or shape bymeans ot' which the door may be swung is secured to the plate 27 by anut 31. Y

Thumb latch draw bolt retracting means are provided to retract the drawbolt irrespective ot' the knob or lrey operated retracting means andcomprise a thumb .piece 32 pivotally mounted between ears 33 formed onthe inner side ot plate 27, a stem 34 that extends inwardly 'trom thethumb piece 32 into a slot '35 formed in the tube 3. A wedge block 36 isslidably mounted in the tube 3, and rests by gravity against the stem34. A iller plate F is secured Ato the tube 3 by rivets G and torms abearing block against which the wedge block 36 slides.

The vupper surface of the block 36 is inclined at an angle a-s at 37`Fig. 4, the purpose of which will be further described.

A finger 38 is pivotal-ly mounted in the tube 3 on a pin 39 whichextends through the tube 3 and is riveted thereto. The upper end ot thelinger 38 engages the crosshead 4. while the lower end thereof isprovided with a roller 40 which rests against the surface 37. Spacingmembers H retain the linger 38 in a central position in the tube 3.

lvl-ien the thumb .piece 32 vis depressed vthe stern 34 will move theblock 36 upwardly and the surface 37 will engage the roller 40 and torcethe finger 38 to -fmove to the dotted line position shown in 'Fig 4 andthus retract the draw 4bolt 4.

The thumb piece will operate to actuate the cross head member entirelyindependently of the knob 18 or key lock 21.

It desired the thumb latch retracting means may be locked from theinside of the door, against operation` by means ot a loelring pin 41.which is journalled in the tube 3. and projects through the plate Oneend oli lthe pin 41 is provided with a head a to prevent. withdrawal ofthe pin 41 and the other end of the pin 41 lis flattened as at b toreceive aV linger 42 which has a sliding lit with said flattened end.The iinger 42 is rotatably mounted in plate 24 and l (ll) lli) issecured thereon by a collar a which has a drive fit on a shank 0 formedon the linger 42, and provides means whereby said pin il may be`rotated.

`A recess 43 is provided in the pin il to receive lthe linger `38 whenthe linger 58 is moved to retract the draw bolt.. By rotating the pin 4lto move the receee 43 away from the linger 38, the solid portion of thepin 4l is moved into `the p: th ot the linger 38 and will preventmovement oil the ling ,r on its'pivot. The pin tl it will be noted onlycontrols the operation oi' the thumb latch re tracting means and thedraw bolt may be retracted by either the knob or key operated retractingmeans.

However, I also provide means controlled from the inside oi' the doorwhereby the draw bolt may be looked against operation by `any of thehereinbefore mentioned retracting means, and auch locking' meanscoinprise a lock bolt 44 iouinalled m the body l adjacent to andextending through a portion of the sleeve 5. The lock bolt 4d isidentical to that shown in my copendint;` mgplication and is provided atone end Wfth a head tt' to prevent withdrawal. and at its other end witha flattened portion e that extentie through the plate Q4- and ie adaptedto slidingly receive a linger 45 which provides means whereby the lockbolt tl may be rorated. The finger 45 ie identical in conetruction andassembly to the finger The sleeve 5 is provided with a transverse notchlo into Whichthe pin 44 is adapted to be rotated to thereby preventreti1A ction oit the draw bolt.

The lock bolt 44 provided with a recess1 47 which is adapted to normallyaccommodate the sleeve 5 and permit :tree movement of the sleevetherethrough.

y rotating' the lock bolt id to bring the recess 4i' out oi' alin-ementwith the Sleeve 5. the body of said pin is presiented to said sleeve andenters the notch etti' in said sleeve to lock the same as described.

The operation and assembly of my invention will be apparent from theforegoing de- Seription.
